我正在尝试实现 DirectoryNamer,但不幸的是,这会导致出现错误消息,我不知道下一步该做什么。
控制器(摘录):
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($image);
$em->flush();
//...
}
DirectoryNamer 服务类:
use Vich\UploaderBundle\Naming\DirectoryNamerInterface;
class ArtistDirectoryNamer implements DirectoryNamerInterface
{
public function directoryName($image, PropertyMapping $mapping) {
return $image->getArtist()->getId();
}
}
VichUploader 配置:
vich_uploader:
db_driver: orm
mappings:
upload_artists:
uri_prefix: /upload/artists
upload_destination: %kernel.root_dir%/../web/upload/artists
directory_namer: macms_admin.artist_directory_namer
namer: vich_uploader.namer_uniqid
inject_on_load: false
delete_on_update: true
delete_on_remove: true
...以及由此产生的错误消息:
编译错误:ArtistDirectoryNamer::directoryName() 的声明必须与 Vich\UploaderBundle\Naming\DirectoryNamerInterface::directoryName($object, Vich\UploaderBundle\Mapping\PropertyMapping $mapping) 兼容
我的代码有什么问题?在我实现 DirectoryNamer 之前,上传工作正常,文件已存储在“/upload/artists”中。
有什么提示吗?提前致谢!
